Title: Tomato Blight
Post by: Roy Bham UK on August 26, 2005, 21:05:10
Please don’t tell me this is Tom Blight as I have only just received my first red tomato.
Edited to re-phrase ;D Could anyone tell me what these marks are on my tomato leaves please? ;D

One thing for sure, Roy - it's NOT blight!

Roy, I've had marks like that on and off over the summer but the toms (Gardener's Delight) have been happily ripening, and taste great, so I'm not worrying about it  :)

Looks like some sort of physical damage Roy. Possibly damage from random feeding of some pest or it may be sunburn or wind damage. I would keep an eye, or both if you can, on that marginal chlorosis in the first picture though.

;) Thanks Guys, that's a relief I think? This is the plant I mentioned in an earlier thread that had a broken truss, could this have caused it? I can't recognise the marginal chlorosis as I have never seen it before, the first piccy is of the same leaf branch, what does it look like John? ???

The right hand leaf has a small yellowing patch at the bottom right while the centre leaf has some at the tip and also at the lower left marginal indent. This can be indicative of infestation by blight or other diseases and disorders. I cannot imagine how a broken truss would have any influence over this though.
I know you will probably appreciate this Roy. I have been so intently watching a Colocasia escelunta "Nancy's Revenge" for signs of it's spectacular colour developing before cooler temperatures arrive that I missed damage similar to your pictures. Today I noticed the damage and a small number of RSM's on one leaf- perhaps you should check your plants?

 :( Hmm! still not out of the woods then ??? Thanks for the warning of disease on other plants, I must admit I have been neglecting them since having the Lottie.

Just checked my Alocasia macrorrhizos (Giant Elephant Ear) one of very few plants kept in doors and it appears to have wooly aphids or a bad dose of cobwebs, I think this may be why it is yellowing around the edges? how would you tackle this?

::) Silly me of cause it is, I'll shove it outside and give the leaves a mist of water, regularly and see if that helps and hope there's some predators out there. ;D

Thanks Tim. ;)
